trying to get pregnant without him knowing.

So my husband and I just got married on the 29th. I'm not on birth control and he knows that but I watch my cycle to see when I'm ovulating. I have sex with him every chance I can because I want to be pregnant. But I haven't told him any of this. I'm not sure he wants a baby right this min but I do. He's in the army and will be deployed again soon I don't think he wants to be away for all of that. But I really want a baby now. Is it like betrayal trying to get pregnant without him knowing?
